一种基于CMOS图像传感器的照度测量方法
A Method of Measuring Illuminance Distribution Based on CMOS Image Sensor
摘要
Abstract
The feasibility of using CMOS image sensor combined with digital image processing method to obtain environmental work illuminance is studied. The relationship between the output value, the exposure time and gain exposure is analyzed, and the environment illumination measurement method is determined. For the actual needs of the project, the image acquisition and luminance measurement system based on CMOS sensor OV7670 are designed and the method of system calibration and parameter identification is researched, which can realize fast measurement of intensity of illumination. The results show that the method can fast measure the environment illumination, and meet the requirement of accuracy of measurement.关键词
